unit for floor lamps, table lamps and various other kinds ot' fixtureswhere pull chain sock? ets have generally been previously employed, Theobject of the present invention is to provide a single unit two waysocket which will eliminate and render unnecessary much ot' the wiringand the addition of pull chain sockets which have heretofore beennecessary. l l

lA further obj ect of the invention is to provide a two way` socket unitof this character equipped with means for enabling it to be readilymounted inposition on the standard of a Vlamp or analogousportion otother lixtures and' provided also with means for clamping a lamp `shadein position.

Another object of the yinvention is to equip the two lway socket unitwith an interiorly arranged switch mechanism having means l0- catedeXteriorly of the lamp shade at the top thereoic for operating theswitchV lVith these and other objects in view the invention consists inthe construction Vand4 novel combination and arrangement of partshereinafter fully described and illustrated in the accompanying drawingsand pointed out in the claims lieretojappended, it beingl understoodthat various. changes in the form7 proportion and minor details ofconstruct-ion within the scope of the claims may beresorted to withoutdeparting from the spirit or sacrificing any of the advantages of the'invention.

l In the accompan ingdrawings l illustrated the pre erred embodimentofthe invention, the two way socket unit is provided with an insulatingbody l, constructed of molded bakelite or other suitable insulatingmaterial and consisting of an approximately cylindrical upper portionand downwardly di'vergingintegral sockets 2 and having at the bottom'acentral'depending neck 3. v'I'hedepending bushing receive the upper endof 'a inetal vtube (if or other portion of a lamp or iixture. The metaltube '6 which Vforms a. support for the 'two way socket unitalsoprovides-a conduit for the wires fr' and 8 whichlare connected with andcontrolled the `switch mechanism hereinafter described. The threadedbushing is preferably embedded in 'the insulatedbody during the moldingoff the latter and in practice the twoway socket unit will be suppliedto the trade vwithout the conducting wires as will be readilyunderstood. The conducting wires,'the 'metal tube 6, and the lamp shade(9 being shown in the drawings for the purpose of illustrating theapplication of they invention 'to a floor or similar lamp but the twowaysocket unit may ybe Nemployed for various kinds of fixtures and n'ilaybe readily connected Athereto as will be readily understood. The hollowcylindrical upper portion, of the insulating body houses the switchmechanism hereinafter described and is provided at opposite sides withvertical ribs 10, forming seats for and supporting the upper transversebar l1 which torins'tlie upper bearing for a operating shaft 1 2.The'upper transverse bar-w'vhich extends across ythe body l at the topthereofis rigidly secured in position upon the said ribs by screwsengage threaded apertures `112.1; `in .the upper ends of the verticalsupporting ribs of the insubtilis bedr The 111511.81' edge ef the bodyis cylindrical and horizontal and the supporting barfll which is locatedadjacentto ,the

upper edge ,of the body,- is .provided with 4al cent-ral exterioijlythreaded sleeve l5 which.

forms the herring` for the-rapper por-tien of" the switch Operatie Shaft112 eed which is also adapted ltoreceive ashade demping in which is neckhas mounted yin it a metallic which is interiorly threaded at 5toV 16.The shade clampin disk 16 is provided with a ccntral'threadet opening 17and it screws on the exteriorly threaded sleeve 15 and is adapted toclamp the lamp shade 9 betweenit and the ripper Vedge of the insulatingbody. The shade clamping disk is preferably of the same diameter as theupper `end of the body and it forms a cap or closure for the same. Theclamping disk 16 is provided iny its upper face with a central circularrecess 'Y 18 which is of a diameter to receive the switch 'operatingbutton 19 having embedded in its lower face ya threaded sleeve 2O forengaging the upper threaded end 21 of the switch operatingshaft 12. Thebutton is preferably recessed at its lower face as shown to provide aperipheral flange 22 which preferably extends into the recess of thevclamping disk but the switch operating button may beY arranged inspaced relation with the upper face of the disk as will'be readilyunderstood. YWhen the button issecured on the upper -end of the switchoperating shaft it is adapted to be turned to rotate the shaftfforoperating the switch as hereinafter fully described.

The switch operating shaft 12 has an intermediatesquared portion 23 forthe reception of a rotary switch member 24 and has round upper and lowerportions 25 and 26 which are journaled respectively inthe uppertransverse bar 11 and in a center bearing opening 27 of a stationaryswitch member 28. The stationarykswitch. member 28 consists of atransverse bar having a central circular enlarged portion provided withcurved ratchet teeth 29 which are approximately triangular and which areadapted to be engaged by blades 30 of the rotary switch member'. Theratchet teeth 29 are .preferably four in number and two opposite teethare providedwith stationary contacts 31 and 32 consisting of plates orpieces of conducting material hav-f ing attached portions which aresecured to the end portions of the stationary switch member by screws 33and 34. The screw 33 constitutes a binding screw'for securing the wire 7to the stationary contact 31 of the switch.

The other screw 34 secures the stationary switch member to one of a pairof transverse conductor bai-S35 and 36. The rotary switch member 24consists of a'central circular hub having a square opening to tit thesquared portion of the shaft'and provided at its, pe-y riphery withthe'vswitch blades30 which are curved "and arranged at a slightinclination as shown to fit the ratchet teeth of the stationary switchmember. The ratchet teeth extend upwardly from the stationary.,

switch member and present' yinclinedfaces to the switch blades andvertical edges` whichform stops for `preventing retrograde movement ofthe rotary switch member. The'hub may consist'of a metallic diskhavingthe' .integral blades asv shown, and upper and lower rings ordisks 37 and 38secured` gagement with thestation ary switch member bymeans of a coiled spring 40 arranged on the lower portion of the switchoperating shaft. and interposed between the upper transverse barand therotary switch member. The upper end of the spring is arranged withinlugs 41 rigid with and projecting downwardly from thel upper transversesupporting bar. When the switch operating shaft 'is rotated the bladesare carried over the teeth of the stationary switch member and are carried into electrical contact with the stationary contacts and out ofcontact with the same to close or breakthe circuit as desired.

The conductor bar 35 which is constructed yof suitable material extendsacross theubody bar 36 has inclined upwardly extending terminalIportions 46 which are connected by suitable fastening devices 47 withthe flanges 48 of screw shell contacts 49. The lower conductor bar iscentrally connected with the lower end 50 of an upwardly extendingconductor bar 51; which is provided at its upper end 52 with ahorizontally disposed port-ion carrying a binding screw 53 for securingthe wire 8 tothe conductor bar 51. The conductor bars connect the centerand shell contacts of the sockets and the conductor bar 35 is providedat its end 43 with a terminal portion 54 to which the stationary switchmember issecured bythe screw which secures one of the stationary switchcontacts to the stationary switch member. The stationary switch memberis provided at the opposite end from that which is attached to theconductor bar, with a depending portion 55 which rests upon theconductor bar 35 and supportsthat end of the stationary switch member.lVhile the socket unit'illust-ratedin the accompanyying drawings isshownprovided with two opposite sockets yet it will be readilyunderstood that the number ofthe sockets may be varied as will bereadily understood.
